Hello Everyone,

After trying to fix all possible issues like timeouts, EOF, errors, panic and other random problems (I had all of them around 300 fails during oc cluster up) I revert my vm to state before installing of below things and I've done it in correct way I guess because now it works like it should from the beginning (+ I can do oc cluster up/down without stress) :)

PS. It can be also limit 100 pulls of Docker image from Openshift (try docker run hello-world).

sudo apt update && sudo apt upgrade (the most important step !!!)

sudo apt install curl curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

sudo apt update && sudo apt -y install docker-ce

sudo usermod -aG docker XXXX

groups XXXX

wget https://github.com/openshift/origin/releases/download/v3.11.0/openshift-origin-client-tools-v3.11.0-0cbc58b-linux-64bit.tar.gz

cat << EOF | sudo tee /etc/docker/daemon.json { "insecure-registries" : [ "172.30.0.0/16" ] } EOF

sudo systemctl daemon-reload sudo systemctl restart docker

sudo systemctl is-enabled docker sudo systemctl is-active docker
